July 29, 2015  Using a climate model that can tag sources of soot and track where it lands, researchers have determined which areas around the Tibetan Plateau contribute the most soot -- ... read more

July 20, 2015  The volume of Arctic sea ice increased by a third after the summer of 2013 as the unusually cool air temperatures prevented the ice from melting, according to scientists. This suggests that the ice ... read more

June 3, 2015  Operation IceBridge wrapped up its seventh Arctic deployment on May 21, when NASA's C-130 research aircraft with the mission's researchers and instruments on board departed Thule Air Base ... read more

June 3, 2015  Each summer, Greenland's ice sheet -- the world's second-largest expanse of ice, measuring three times the size of Texas -- begins to melt. Pockets of melting ice form hundreds of large, ... read more

June 1, 2015  Researchers looking for carbon in equatorial ice cores have found diatoms, a type of algae. Their presence is evidence of what the landscape around the Andes in Peru might have been like more than a ... read more

June 1, 2015  In northwestern Greenland, glaciers flow from the main ice sheet to the ocean in see-sawing seasonal patterns. The ice generally flows faster in the summer than in winter, and the ends of glaciers, ... read more

May 27, 2015  If greenhouse-gas emissions continue to rise, glaciers in the Everest region of the Himalayas could experience dramatic change in the decades to come. Researchers have found Everest glaciers could be ... read more

May 26, 2015  A new light has been shed on the stability of the Antarctic ice sheet. It shows for the first time that ice rises (pinning points that keep the floating parts of ice sheets in place) are formed ... read more

May 21, 2015  Scientists have observed a sudden increase of ice loss in a previously stable region of Antarctica. The ice loss in the region is so large that it causes small changes in the gravity field of the ... read more

May 18, 2015  The grounding of a giant iceberg in Antarctica has provided a unique real-life experiment that has revealed the vulnerability of marine ecosystems to sudden changes in sea-ice cover. Scientists have ... read more

May 13, 2015  A decade-long scientific debate about what's causing the thinning of one of Antarctica's largest ice shelves is settled this week with the publication of an international study in the ... read more

May 5, 2015  Geographers have developed a novel measuring system relying on two different physical methods that promises to enhance forecasting of avalanches and spring floods. The method combines GPS and radar ... read more

Apr. 30, 2015  A multinational study attempted to gauge the population trends of Arctic marine mammals and changes in their habitat, identify missing scientific information, and provide recommendations for the ... read more

Apr. 29, 2015  A new study using evidence from a highly detailed ice core from West Antarctica shows a consistent link between abrupt temperature changes on Greenland and Antarctica during the last ice age, giving ... read more

Apr. 20, 2015  Before Deepwater Horizon, scientists didn't know that oil and marine snow had anything to do with each other. "Marine snow is like dust bunnies in the house," explained a research ... read more

Apr. 17, 2015  Climate models calculate a changing mix of clouds and emissions that interact with solar energy. To narrow the broad range of possible answers from a climate model, researchers analyzed the effect of ... read more

Apr. 14, 2015  Early schemes to model the Greenland and Antarctic ice sheets and their impact on sea levels failed to accurately account for changes caused by snowfall and snow melt. These changes depend on ice ... read more

Mar. 27, 2015  Cold snaps like the ones that hit the eastern United States in the past winters are not a consequence of climate change. Scientists have now shown that global warming actually tends to reduce ... read more
